AUTOMATIC YVEIGHING-MACHINE.

To all whom it may concern."

Be it known that I, PETRONELLA En'rnAUnn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful -lmprovements in Automatic Weighing-Machines, of which the following is a clear, full, and exact description.

My invention relates to automatic weighing machines which, when set to measure a quantity of a given commodity. by weight, will repeat the weighing process as long as the supply of the commodity lasts unless sooner stopped.

The object of my invention is to make the movement of the centrally divided weighingreceptacle actuate the mechanism that sinniltaneously drops thebotto n of one compartment thereof and closes the bottom of the other, and vice versa; to provide simple mechanism for controlling the size of the discharge opening of the overhead hopper anrhplirect the discharge therefrom into the center of the weighing receptacle, and to so simplify the construction of the actuating mechanism of the machine as'to greatly reduce the cost thereof and insure its satisfactory operation. This I accom plish by the'means hereinafter fully described',and as particularly pointed out in the, claims. 1

In the drawings l igure 1 is a front elevation of my invention, Fig. 2 is a perspective view of the segregated hopper used in connection with the same. Fig. dis a side the standards of the snpporting-fran'ie of my invention, which, at their upper ends are provided with horizontal arms that, for a short distance from the standards, bend toward each other and then extend parallel and support a suitable hopper B between them. .The sides of the hopper B depending below arms a converge toward each other,

- and the lower edges of the longitudinal sides thereof are provided with corresponding downward projecting aprons i), b. At the point where these aprons attach to the hopper they are provided with horizontal Specification. of Letters Patent; Paige-p t ed Ben. 14, 1%09,

Application filed. December 31, 1908. Serial No. 470,161. I

guideways for the accommodation of the longitudlnal edges of a longitudinally refiat plate the length of which is, preferably, about twice the length of the hopper, and which is provided with a suitable opening therein, shown in dotted lines, F 2, corresponding to the opening in the bottom of the hopper. Immediately below slide C, the aprons I), b are provided at each .end with suitable bearings for the transverse rock shaft 0, c, which, between said aprons Z), I), have corresponding rectangular leaveslcl'projecting'therefrom that direct the cd-rrent of the commodity falling from said hopper always into the center of said weighingaeceptacle. These leaves (Z are moved nearer to or farther from each other, according gas de-' sired by means of arms D, D, projhcting from corresponding ends of said shafts 6 plane of the leaves d; The upper portions of arms I) have longitudinal slots d there in and said arms are secured together by a thumb-screw c passing through said slots a. and through the vertical slot of ahanging frame E, located in the vertical plane midway between shafts c, c, and having its upper end secured to the adjacent end of the hopper. 'By loosening the thumb-screw and moving it up or down in frame E, 511 11131), will be moved and the leaves correspondingly moved to or away from eachother.

Receptacle or bin, F, into which thecommodity from the hopper discharges, has, preferably, a rectangular upper portion or body, and a lower portion 7' thesides ofwhich converge toward each other. The lower edges of the inclined sides of said lower portion delinethe sides of an opening X in the bottom of said bin, and the front and rear of these lower edges are inclined downwind from each end to a point intersected by the vertical plane located midway between the sides of the bin. This opening X is closed first 'on one side and then on the cated mid way between the sides of bin F, by a rocking-chute G, which latter is mounted upon a shaft o, journaled in the lower ends of hangers h depending from suitable plates attached to the outer surface of the front and rear of said inclined sides, and; this each side of shaft 9, and has its longitudinal chute G has its floor inclined downward on I "sta rcase eraa ns garnai castes.

ciprocal slide (J, which latter consists of a toward each other at the same angle to the other of the longitudinal vertical plane 10- 1 of cmmnmlity has accumulated, and to close closes one-half of said discharge opening and ments by a longitudinal vertical partition H sions to the full compartment and direct the cimnnodity (falling from the hopper) into sides provided with opposite flanges that are outside of the edges of discharge opening X, substantially as shown. The length of chute G is greater than the length of said dis charge opening, and when it is rocked to the limit of its movement in one direction, it

opens the other halit' thereof.

Bin F isdivided into two equal compartlocated in the vertical plane striking longitudinally through the axis of the shaft '9, and it extends upward from the lowest point of the lower transverse edges of said discharge-opening to a point near the upper edges of said bin. Immediately above the upper end of this partition, and in the same longitudinal plane thereas,,there isa rockingshaft J whose ends are journaled and extend through hearings in the side-walls of bin F, and. securely mounted upon this shaft J is a tilting-chute I that is adapted to tilt or incline toward and discharge the commodity flowing into it, first into one compartment of bin 1 and then into the other.

The binF is carried by and between the parallel arms 7r: or bifurcations forming one half of'a graduated halancebeam K, which latter is fulcrumed by having knife-edged trunnions projecting from arms near their shoulders. The portion of said beam opposite the bin is graduated. and otherwise constructed substantially like the balance beam 01 the ordinary scales, excepting that the back of the hooked end thereof is provided, at its highest'point, with a boss, that has an u nvardly projecting screw mthat extemls freely through a suitableperforation in the end oi. an overhanging arm M, projecting 'lroma plate connecting the upper ends of standards A. The upper end of screw in has a thumb nut 11 mounted thereon, by propcrly manipulating which the extent of the '\-'il)rntion of the beam K can be regulated;

lVhcntZthe weight of the commodity in bin l issi-idlicient to m'erhalancc the grad ualcd part of the heann-saidhin will move downward, and it this downward movenu-nt. that is utilized to roclt the rockingchute (l, and permit the discharge of the compartment, in which the desired weight the other one, and at the same time rock tho tilting-chute sons to prevent further acccsthe compartment just closed. 't'o accomplish this I sec-lire on the end of shaft l nearest the stamlard, depending arm tends downward at right angles to the plane l of the floor olitho rhui'o in. suitable distance, l and has its lower portion provided with a I longitudinal sloth; This slot engaged by headed stud or screw, 4), jn'ojccting from an upper cud of an arm l g'n'ojecting up l N, that cx- BEST AVAILABLE COPY from. the rocking-chute (if Thelower end.

vwhich are bent toward and secured to the adjacent upwardly flanged edge of said chute G at such points on each side of its pivot that said arm 0 will extend upward at right angles to a horizontal plane connecting the ends of said chute. Thus when said chute G is at the limit of its movement in one direction, arm P will incline toward one side of the plane of the partition H, and "when the chute is at the limit of its movement in the opposite direction the arm I? will incline at about the same angle to the opposite side of said partition. The upper extremity of arm P, above stud O, is bent substantially at right angles to the p to provide a flat blade, the extremity of which is adapted to be engaged by one or the other of the vibrating trips, which latter are arranged in the same horizontal bin F on one side of the vertical partition H, and the. other oted a corresponding distance on the other side of said vertical plane. These trips have a horizontal branch that extends from the pivot thereof away from the vertical plane plane of of the. partition to points beyond the'sides of the bin a suitable distance and rest. upon horizontal arms Q, projecting from standards A, substantially as shown. Said trips also have a shorter branch 'r'that inclines downward. radially from the pivot thereof, such a distance that WllfilitLI'lll P moves toward and arrives at the limit of its movement in one direction, the blade at the upper end ot'said arm will be engaged. by the v 105 extremity of said branch and prevented from moving in the reverse direction until the rompartmeut on the other side of the partiportion belowv the same,"

lane, and one of which is pivoted to the sideof the of which is .piv-

lion has accumulated sutlicient measure of. the commodity to cause the bin F to move dmvnwurd. When bin l moves downward the engagement of the branches g of the trip with arms Q, will move the tripsupv'ard on their pivots sutlicient to raise the hranch r in touch .with arm I out of engagement with the same whereupon the gravity of the commodity being weighed in the compartment on the side ot the partition opposite arui I will rock chute (I to the limit -of its movement in the opposite direction and arm P will move to the other limit 01": its-throw, thus permitlingrthe commodity to be discharged from the recently laden compartment, and enable the bin 1 ward so that the upper extremity of arm P will, while in transit, push past the under edge of the extremity of the branch '1' of the opposite trip and its return movement be prevented by coming in contact with the 'cdgc oi. the extremity thereof. This artion' I of the. weighing bin, I, andthe means for to move upuni ait'ecting: the alternate closure of the discharge openings of its two compartments,

and causing thedischarge from the overhead hopper to flow first into oneclosed compartment and then the other, will continue as long as there is sufficient flow of the commodity, or until the same is stopped. The" commodity discharged from recep-' tacleF'empties into a funnel R that is supported by means of lateral studs 8 projectlng ltrom' near 'its'upper edge, that extend 'i'ii-through a vertical slot 1; in the vertically disposed end portion of T-shaped'arms S rejecting. from the standards A, 'substan tially as shown. The outer port-ions of these istuds *8 are threadedand engagedby'thumbi jnuts 'r; by means of which the funnel-may be i 1 adjuste' ;l 'to any vertical position desired.

"lir order" to facilitatepjthe removal of the gdesired I have providedthe vertical inemereof the T 'sha ed arms S with an offset t udsis can be easily removed. To revent the receptacle F from, rocking during the Loperat-ion of the machine I connect the same by links WV to the. standards A, thus permitting the vertical movement of said re ocptaclejbut preventing anyradial 'move intuit thereof; i I donot desire to be confined to the exact construction ofthe essential features of the weighing.machinefto which m improve- "ments are applied as they may 0 changed without departing from the spirit of my tained from experiment thatthe best "results are accomplished by so doing. The vertically disposed edges are fitted in suitable retaining grooves so that they can he slid in or out as desired, and in order to prevent. the overhead hopper interfering r with its withdrawal I prefer to slant it away .fromthe central partition H so that its upper edge will be farther from partition II than its lower edge, substantially asshown.
